Hi,
Something like "find ... -mtime +1 ..." finds files that changed more than one day ago. The number specifies a number of 24 hour periods, so if you specify "+2" the file has to have been changed more than 48 hours ago. The resolution of the time comparison only goes as low as a day.

So:

touch -m 09180000 wtupa.tmp

ls -l wtupa.tmp
-rw-rw-rw- 1 pete devel 3 Sep 18 00:00 wtupa.tmp

find . -name "wtupa.tmp" -mtime +2 (nothing found)

touch -m 09171705 wtupa.tmp

find . -name "wtupa.tmp" -mtime +2
result ---> ./wtupa.tmp

and the date is
Mon Sep 20 17:05:09 BST 2004

Regards

Pete

[leprod:> ls -la /dbdumps/backups/df*

-rw-r----- 1 oracle dba 5256142848 Sep 18 07:12 /dbdumps/backups/df_t51

When I use:

[leprod:> find /dbdumps/backups -name "df*" -mtime +0 -print
/dbdumps/backups/df_t537174441_s1_p1
[oracle_at_dohsdb10]:/usr/oracle/tools/bin

When I use anything other than +1 or more the file isn't found. However, the system date is Sep 20. Yet the last modified time was the 18th.

What am I missing?
